Executive Summary | Ultraviolet lasers operating around 200nm are becoming more common. This is due to both the utility of these lasers and the increased manufacturing capability allowing their production. The spectrum of UV light includes wavelengths shorter than violet light at 380nm. The frequency for wavelengths below 380nm results in radiation with a very high ionization potential. Optics to support these applications must survive high laser fluence for extended periods under the ionizing radiation of these UV lasers. Plasma Optik has manufactured ion beam sputtered (IBS) UV coatings for applications in these wavelength ranges and the status of this effort is discussed.
